Claims.

This invention relates generally to improvements in cash registers andhas particular reference to improvements in the diiierential andprinting mechanisms of such machines, and is a 5 division of anapplication for Letters Patent of the United States of Frederick L.Fuller, Serial No. 161,752, iiled January 18, 1927.

The principal object of this invention is to provide an improveddifferential mechanism which may be utilized for the purpose ofadjusting type carriers and indicators as well as actuating accountingmachines. In machines of the type used herein for the purpose ofillustration it is considered advantageous and desirable, if notaltogether necessary, to provide means whereby the keys during theirinitial movement may be operated independently of the differentialmechanisms. This idle movement is particularly important since itpermits other mechanisms to be actuated prior to any registeringmovement of the differential devices and the time which it allows may beemployed for a number of purposes, among which may be stated; thelatching of the desired keys to the key coupler, the unlocking of thedifferential actuators, the engagement of a totalizer with theactuators, etc. Moreover, in respect to the printing functions of themachine, it is desirable that the adjusted type carriers be retained intheir differentially adjusted positions when the keys have completedtheir downward strokes so that printing may be properly effected at thistime.

Prior to the present construction, it has been the practice to providethe cam slots which cooperate with members operated by the keys withdwells at each end of the cam slots. This permits an idle movement ofthe keys at the beginning and end of their strokes for performing thedesired functions. It is the purpose of the present invention todispense with the dwells and to provide a mechanism whereby the camslots may be continuous so that immediately upon the movement of themember which cooperates with the cam slot the differential actuatorswill be moved.

In the present construction in order to provide for the idle movementbetween the keys and the diiferential actuators, the member whichcooperates with the cam slotted element, has a pin and slot connectionwith the related key, the parts being so arranged and designed that eachkey may be operated initially without eiiecting any movement of itscooperating member. For the purpose of illustrating and describing the55- -utility of such devices this mechanism is shown in connection withdevices whereby the keys may be latched to the key coupler during theirinitial movement at the same time that the actuator locking devices arereleased. The differential actuators are shown in connection withprinting 5 mechanisms whereby they may be utilized for the purpose ofdifferentially adjusting the type carriers as well as the accountingelements.

In respect to the printing mechanism of the machine it is also an objectto provide a simple and effective printing mechanism whereby the itemsmay be printed upon a record strip as well as to provide a simple andeffective mechanism for printing of the totals upon the record strip.Among the many features embodied in the iml5 proved printing mechanismmay be mentioned, an improved paper supply frame which may be bodilyelevated from its normal position whereby access to the paper supply mayreadily be had. Furthermore, in respect to the improved paper feedingdevices, the latter are so arranged that during the down stroke of thekeys a portion of the paper is drawn from the storage roll therebyrendering a certain amount of slack in the paper. During the returnstroke of the key and after the items have been printed the slack istaken up by winding the paper upon the storage roller. Thus by dividingthe paper feeding movements between the strokes of the keys the hardoperation which would result otherwise is reduced to a great extent.

In the accompanying drawings the improvements are shown applied to amachine of the same general type as is shown and described in the UnitedStates application, Serial No. 263,125, i'lled November 19, 1918, byFrederick L. Fuller, and issued January 7, 1930 as Patent No. 1,742,701;and British Patents Nos. 135,465, 140,363, 157,823, 157,824 and 157,825of July 14, 1921, covering the same inventions. However, as will be moreclear- 40 ly apparent later on, the inventive ideas are capable of beingembodied in a variety of mechanical structures, and it is to beexpressly understood that the drawings are designed for the purpose ofillustration only, and not for the purpose of elements of which are setforth in appended claims and a preferred form or embodiment of which ishereinafter described with reference to the drawings which accompany andform a part of this specification.

General construction The machine taken for the purposes of illustrationis provided with a number of operating keys divided into denominationalgroups and if so desired special keys may also be included, but

for the purpose of the present invention these need not be described.The amount keys 24 are all pivoted upon a transverse shaft 25 which iscarried by the framework of the machine, this shaft forming the pivotalpoint of the keys which are guided in their reciprocating movements attheir forward ends by slots 26 formed in a cabinet 2l and at theirrearward ends by slots 28 formed in a plate 29 attached to a portion ofthe framework 30. Each of the keys 24 is formed with a square notch 3|adapted to receive the flange 32 of thekey coupler 33 when the latter iselevated by a depression of any of the operating keys. The key coupleris pivoted at 34 between the side frames of the machine and, as will benoted, the

pivotal points of the shaft and key coupler are displaced with respectto each other so that the flange 32 of the key coupler will intersect anarc described about the key shaft as a center and passing through theforward end of the upper shoulder forming the notch 3|. This is for thepurpose of coupling the keys so that a complete depression of a singledetached key will result in a simultaneous depression of all the keyswhich have been attached to the key coupler in a manner to be describedhereinafter.

Connected to the key coupler 33 is a plate 35 carrying two sets ofoppositely disposed rack teeth 36 which are adapted to alternatelyengage the teeth of a pinion 3l fast to a driving shaft 38 which is alsosuitably journaled in side frames of the machine. The connection is suchthat when the key coupler is rocked by the keys the rack 35 is raisedand lowered so that the reciprocating motion of the key coupler will beconverted into a rotary motion of the shaft 38. The device foraccomplishing this need not be described herein in further detail asthis sort of mechanism is well known in the art and shown in manypatents. For details of construction and operation of one form of theabove, reference may be had to the patent to Thomas Carney, No. 482,461,dated September 6, 1892.

In nearly all forms of cash register construction it is considereddesirable that after a registration has commenced some devices beprovided to compel a complete performance of the started registrationbefore a second operation can be effected. To this end there is securedto the main operating shaft 38 (Fig. 2,) a ratchet wheel 39 againstwhich bears a spring-pressed pawl 40 for preventing any retrogrademotion of the shaft 38 and thus insuring a complete operation of themachine when once started.

Dierential mechanism In machines of the class described, the operatingkeys usually have associated therewith a differential mechanism wherebythe keys may differentially adjust type carriers, actuate totalizingmechanism, and control the displaying of indicators so that fullinformation relative to the keys operated may be available in variousforms. The machine as herein disclosed is provided with a novel form ofdifferential mechanism which will now be described in detail.

As will be noted in Fig. 1, each of the operating keys 24 is providedwith an extension 4| directly over the key shaft 25. It will also beobserved in Fig. 3 that each key 24 is pivotally mounted upon a collar42 which is loosely mounted on the shaft 25, the collar 42 havingrigidly attached thereto an upwardly extending arm 43 carrying a pin 44in engagement with a circular aperture 45 formed in the extension 4| ofthe key, it being noted that the aperture 45 is slightly larger than thediameter of the pin 44 which projects therein and that each arm 43 ismounted adjacent its respective key 24. Each arm 43 is provided with aroller 46 in engagement with a cam slot 41 of an associated cam plate48. The cam plates 48 of which there is one for each key are arranged ingroups and those of each group fit in slots formed in a frame 49 looselypivoted upon a transverse shaft 50, the plates 48 being secured to theframe by cross pins 5|. It will be noted from Fig. 1 that the cam slots4l of the various plates 48 are eccentric with respect to the key shaft25 so that as each key of a group is depressed its roller 46 coactingwith the cam slot 4l of its related cam plate will rock the frame 49differentially an amount commensurate with the key depressed. 'I'hus itwill be understood that when a key of the lowest value in a group orbank is depressed the associated cam plate 48 and differential framewill be rocked a unit amount,

whereas when keys of a greater value are op-` erated the frame 49 willbe rocked a greater amount depending on the value of the key operated.

'I'he construction of the differential devices as explained is such thata key may be given a movement independent of the plate due to the looseconnection 44, 45 between the key and the arm 43.

It will be obvious that when the key 24 is slightly7 depressed it willelevate the key coupler 33 to a corresponding extent. As will beobserved in Fig. 1, there is slidably mounted upon the key coupler 33 alatch plate 52 which is urged rearwardly by a spring 53, suitable stopdevices such as shown in the Fuller Patent No. 1,742,701 and Britishpatents mentioned before being provided whereby movement of the latchplate beyond the position shown in Fig. l is prevented. When a key isinitially depressed the rack plate 35 will be raised thereby rotatingthe shaft 38 a partial amount and as the ratchet wheel 39 rotates thespring-pressed pawl 40 will engage one of the teeth of the ratchet wheeladjacent one of the open spaces 54 (Fig. 2). This cooperation willprevent retrograde movement of the key coupler and the shaft 38 and itwill be understood constitutes the means for holding the key coupler inits partially elevated or coupling position.

Each bank or group of keys has associated therewith a latch plate 52 sothat each latch plate may be operated independently of any other latchplate.

Whenever the key coupler has been raised to its coupling point the latchplates 52 mounted on the coupler will be slightly above the notches 3lformed in the rear ends of the keys which have not been operated, andwill bear against the concentric edge 55 of such keys. When it isdesired to attach an amount key to the elevated key coupler the desiredkey is depressed slightly resulting in the raising of the rearward endof the key and by virtue of the concentric edge 55 cooperating with therear edge of the latch plate 52 the latter will be forced forwardlyuntil the concentric edge clears the latch plate 52. At this time thelatch plate will be free to be moved rearwardly under the influence ofthe spring 53 to engage the notch 3| formed in the rear end of thedepressed key. In this manner the amount key is positively engaged orattached to the key coupler and in the same manner amount keysassociated with the other banks may be partially and successivelydepressed so as to latch them to the key coupler which then permits asimultaneous completion of the depression of all the keys which havebeen so attached.

It is considered desirable during the time that the keys are beinglatched to the key coupler that there be no movement of the differentialdevices and that during this time the differential devices which arenormally locked, be unlocked to permit their subsequent actuation by thekeys. This timing element also permits engagement of a selectedtotalizer with the differential devices.

Referring to Fig. l, it will be noted that one of the cam plates 48 of agroup is provided with a projection 56 cooperating with a hook 51 formedas an integral part of a bail 58 which extends underneath the keys of abank and which bail is loosely mounted upon the shaft 25. A spring 59|is provided to urge the hook 51 into locking relationship with theprojection 56. During the time that a key is being initially depressedthe underside of the key coacting with the bail 58 will rock the baildownwardly, thus disengaging the hook 51 from the projection 56, andsince the key will be held in its initially depressed position thisrelationship will be maintained.

As will be observed in Fig. l, when an amount key 24 is partiallydepressed for the purpose of initially operating the key coupler orlatching the key tothe partially elevated key coupler, the extension 4lwill be rocked about the shaft 25 and due to the fact that theengagement of the roller 46 against the upper edge of the cam slot 41 issufficient to hold the arm i3 from movement temporarily against anyfrictional force existing between the coacting sides of the arm 43 andthe key 25, the key 24 may be operated independently of the arm. Whenthe key has been initially depressed to coupling position the rearwardedge of the aperture 45 will coact with the pin 44.

As the depressed keys are operated still further the rear edge of theaperture 45 coacting with the pin 44 will rock the arm 43 of thedepressed key ciockwise about its pivotal point, and since the roller 46coacts with the cam slot 41 of its respective cam plate the frame 45will be rocked differentially and during this time the rollers 46associated with the undepressed amount keys in the same bank will playin the arcuate slots 59 formed in the related cam plates 48 which permitthe upward tilting of the differential frame 49 without interfering withthe rollers carried by the unoperated keys.

The differential movement of the frame 49 may be utilized for manypurposes and as herein shown is utilized to adjust item type carriersand actuate totalizer elements. Connected to each differential frame isa segment 6i) which, as shown in Fig. 4, is in engagement with a pinion6l rigidly secured to an item type carrier 62 journaled upon a fixedshaft 63. As stated, each differential frame has secured to it acorresponding segment 56 so that when the segments are moved by thedepression of the keys in the related banks the item type wheels 62 willbe rotated correspondingly and, as will be described hereinafter whensuitable impression means are actuated the item type wheels will printcharacters indicating the amount of the transaction entered in themachine.

Printing mechanism The printing mechanism. for printing the itemscomprises a printing frame formed of two side frames 55 and 65 (Fig. 6)which are connected together by a cross bar 61 at the rear ends, and bya rod 68 (Fig. 1) at their forward ends. Each of the frame members 65and 65 is provided with claws 66 (Fig. 7) overlying the shaft 5D. Theforward parts of the side frames 65 and 65 rest upon a tie bar 16. Theframe members 65 and 65 are also connected together by shafts and othermembers which will be referred to hereinafter.

Secured to a shaft 1l (Fig. 4) which is carried by the frames 65 and 66are two rearwardly eX- tending arms 12 and 13 (Fig. 6) which areconnected by a cross head 14 carrying a rubber impression block orplaten 15 overlying the item type carriers 62. Pivotally mounted on astud carried by the frame member 65 is a bell-crank 16 (Fig. 8) which,as shown in Fig. 4, is provided with a roller engaging the race of a boxcam 11 secured to the driving shaft 36. The bell-crank 16 has a pin andslot connection with a second bell-crank 18 (Fig. 8) one arm of which isbifurcated to receive a pin carried by a downward extension 16 of aclutch member 66 (Fig. 6) which is springpressed along the shaft 1l bymeans of a spring 85E. The clutch member 66 is adapted to form theconnecting means between the platen and the operating parts of themachine and is provided with a forwardly extending arm 8i (Fig. 7) towhich is connected a spring 82 which normally urges the platen 15upwardly away from the type.

During the downward movement of the keys the item type carriers will beadjusted differentially and during the time that the type carriers arein their differentially adjusted position the box cam 11 (Fig. 4) willmove through an angle of substantially 180 degrees, thereby bringing thecam position thereof into proximity with the roller carried at the rearend of bell-crank 10. As the operated keys start their return movementthe extensions 4| are moved a short distance independently of the stud44 and the differential mechanism is held in its adjusted positionduring this interval. t is then that the cam portion of box cam 11 willrock bell crank 18, extension 19, and clutch member 80, and consequentlyplaten 15 will be rocked downwardly against the adjusted type carriers,thereby effecting a printing impression upon the record strip. Continuedrestoration of the keys will serve to restore the arms 43 to theirnormal positions thereby allowing the differentially operated frames todrop to their normal positions. It will be understood that since theforward edges of the apertures 45 will be in engagement with the stud 44during the return stroke of the keys that the arms 43 will all bepositively returned to their normal positions.

Printing from the type carriers is effected upon a record strip 83 whichis drawn from a supply roll 84 (Fig. 4) and wound upon a storage roll85. The supporting studs for the rolls 84 and 85 are attached to a framemember 88 (Figs. 6 and 7) which is loosely mounted upon the platensupporting shaft 1|. As best shown in Fig. 4, the record strip 83 isdrawn from the supply rcll 84 over a roller 81 carried by the frame 86thence rearwardly around the platen 15 over the cross bar 14 and thenceforwardly over a roller 88 also carried by the frame 86, and then iswound upon the storage roll 85.

In order to feed the record strip an increment after each printingoperation, the following mechanism is employed. Attached to the drivingshaft 38 is a box cam 90 (Fig. 7) the race of which cooperates with aroller carried by a bellcrank 9| pivoted upon the side frame 55. heforward arm of the bell-crank 9| is bifurcated to engage a pin 92 (Fig.8) carried by a toothed segment plate 93 loosely mounted upon the studwhich forms the supporting means for the supply roll 84. The teeth ofthe segment plate S3 engage teeth formed on a second segment plate 94loosely pivoted upon the supporting stud for the storage roll 85. Theplate 93 carries a feeding pawl 95 in engagement with the teeth of aratchet wheel 9B connected to the supply roll B4 while the segment plate94 carries a feeding pawl 91 in engagement with the teeth of a ratchetwheel 98 connected to the storage roll 85.

During the downward stroke of the keys the bell-crank 9| will be rockedcounter-clockwise (Fig. 7) so that its forward end will be raisedthereby rocking the segment plate 93 counterclockwise (Fig. 8) and bythe engagement of the pawl 95 with the teeth of the ratchet wheel 9B thesupply roll 84 will be rotated slightly so that a portion of the recordstrip will be unrolled. During this time the segment 94 will be rockedin a clockwise direction (Fig. 8) so that the feeding pawl 91 will slipover the teeth of the ratchet wheel 98. During the return stroke of thekeys the forward arm of the bell-crank 9| will be rocked downwardly andsince the segment member 94 will be rocked counter-clockwise the feedingpawl 91 will rotate the storage roll 85 in such a direction that it willwind onto the storage roll that portion of the record strip that hasbeen unrolled from the supply roll and thus bring the printed portion ofthe record strip around the cross head and to such a position that itmay be viewed through a glass carried by a lid 99 (Fig. 4) hinged to thecabinet of the machine. 'I'he glass is provided with a writing slot |00through which written entries may be made in juxtaposition to eachprinted item, the cross bar 14 serving satisfactorily as a writingtable` The inking mechanism for the item printing mechanism of theillustrative machine comprises an inking ribbon |0| (Fig. 6) which isdrawn from a roller |02 (Fig. 1) over the printing type carriers andthen onto a receiving roll |03 (Fig. 6). The inking ribbon |0| issupported over the type carriers by a pair of plates |04 (Figs. 4 and 6)which are suitably apertured so as not to interfere with the printingaction of the platen 15. Any suitable mechanism may be provided forgiving the inking ribbon a step by step movement during successiveoperations of the machine, and since this mechanism forms no part of thepresent invention, it will not be described in the present application.

It will be noted in Figs. l and 7 that the printing mechanism isnormally entirely concealed by the lid 99 and another lid |05 which isalso hinged to the cabinet 21. It is necessary at times to obtain accessto the printing mechanism and particularly the paper supply devices inorder to replenish the supply of paper when exhausted and for thisreason the frame 86 which carries the paper supply and storage rolls isso mounted that it may be swung about shaft 1| as a pivot, as shown inFig. 7, to render the parts accessible.

When the paper carrying frame is returned to l" its normal position itis latched by means of a latch member |06 (Fig. 1) engaging a lug |01formed on the side frame 65.

Situated just forward of the item type wheels 52 and adapted to engagethe segmental racks 60 are pinions |08 attached to the printing wheelsof a pair of totalizers designated as A and B in Fig. 4. Both totalizersare pivotally mounted so that by suitable mechanism the totalizer framesmay be rocked about their pivotal points to bring the totalizer pinionsinto and out of engagement with the actuating racks 00 so that thetotalizers may accumulate the items entered in the machine. Thetotalizers may be utilized for the purpose of registering amounts forseparate departments or clerks and to this end any suitable selectivetotalizer engaging mechanism may be utilized. Since this feature is notdirectly involved in the present application it is not herein shown ordescribed but for one form of mechanism which may be employed for thispurpose reference may be had to the Fuller Patent No. 1,742,701 andBritish patents hereinbefore mentioned.

It is desirable to print the totals accumulated by the totalizers sothat there may be provided an unalterable record valuable for futurereference. It is also desirable to have this information printeddirectly upon the itemized record strip and to this end it is a purposeof the present invention to provide a simple and effective totalprinting means. Secured to a shaft |09 (Fig. 4) extending between theside frames 65 and 60 is a platen carrying frame ||0 carrying aplurality of platens overlying the printing wheels of their respectivetotaliaers. It will be noted that the record strip passes just beneaththese printing platens while interposed between each platen and itsrelated printing wheels is an inking ribbon ||2 (Fig. l) which is guidedand supported by spaced 75 supporting plates H3 (Fig. 4) and carried atits ends by a pair of spools. Any suitable devices may be utilized formanually feeding the inking ribbon from one spool to the other when theimpressions become light. Secured to the shaft it@ is a printing lever li4 (Fig. 6) the lever being so arranged that when it is moved one wayone of the platens will force the record strip and inking ribbon againstthe printing line of one totalizer and when moved in the oppositedirection the other platen will effect a printing impression upon therecord strip from the other totalizer. After this has been performed itis desirable to manually feed the record strip so that the printingimpressions may be brought to view and to this end there is pivotallymounted upon the stud which carries the storage roller $5 a lever H5(Fig. 8) carrying a pawl H6 in engagement with the ratchet wheel 98. Bysuitably reciprocating the paper feeding lever H5 the printed recordstrip may be fed manually so that the impression may be brought to view.As best shown in Fig. l, the paper feed4 ing lever projects through thelid Q9 so that it may be exteriorly operated, this being also used forfeeding the record strip an additional amount when the space provided bythe usual feeding of the record strip by the machine is not sufficientto accommodate the desired autographic notation.

If so desired any suitable locking devices may be provided to lock theprinting lever so that printing operations by unauthorized persons maybe effectively prevented.

While the type of differential mechanism illus-- trated in Figs. l and 3has been found practical and capable of performing the results describedvery effectively, it is to be understood that this is but one embodimentof the invention and that other specific methods and mechanisms maysuggest themselves for accomplishing the same object.

One modification of the present invention is illustrated in Fig. 5'wherein it will be noted that the extension il in this oase ispivotally secured by a pin II'I to the arm #13, the lower end of the armbeing provided With an aperture i ifi slightly larger than the key shaft25. Therefore, it will be obvious that a lost motion connection betweenthe key and the arm 43 is produced through the enlarged aperture H3encircling the shaft 25. When a key employing this type of constructionis depressed the extension iii will be rocked clockwise and due to thefact that the roller Mi is held against movement by means of the camplate the pin IH will rock the lower end of the arm d3 forward until therearward edge of the aperture I I8 coacts with the periphery of the keyshaft This movement of the key independently of the roller 4G issufficient to latch the key to the coupler and to perform otherfunctions such as unlocking the differential actuators, selecting atotalizer for operation, etc. It will be obvious that the lost motionconnection is also effective at the beginning of the return stroke ofthe keys so that the type carriers will be held in their adjustedpositions while printing from these type carriers is being effected.

In describing the construction of the mechanism comprised by theimprovement it has been necessary incidentally to give a thoroughexplanation of the operation of the different devices. llt is thought,therefore, that the usual summary of operation may, in this case, beomitted.

While the form of mechanism herein shown and described is admirablyadapted to fulfill the objects primarily stated, it is to be understoodthat it is not intended to confine the invention to the one form orembodiment herein disclosed, for it is susceptible of embodiment invarious forms all coming within the scope of the claims which follow.
